My feeling is that any big bang for the buck is over, it was a wild ride. Volatility still seems to be with Bitcoin, looks like there are still opportunities ($6200 a month ago, $11,450 right now). But it's mostly gambling, without the M Life. I'm still using Coinbase, which takes 1.5% going in and out. Square claims to be fee-free, but I noticed that I paid about 1% more to buy bitcoin from them than Coinbase was asking. Robinhood is coming with fee-free bitcoin purchases, I'm pretty impressed with them. I'm pretty much just hodling on right now.
